NIS Refinery in Pancevo, Serbia

Sarens performs series of intricate operations at the
NIS Refinery in Pancevo, Serbia

Serbia's Naftna Industrija Srbije (NIS) JSC, began construction
of its bottom-of-the barrel (BOTB), complex as part of its
modernisation programme to improve energy efficiency and increase
production of higher-quality products, ensuring operational
reliability at its 4.8 million-tonne/year refinery at Pancevo. Once
operational, the 2,000-tonne/day BOTB complex will increase
Pancevo's processing efficiency from a current 86 to 99.2 percent
as well as increase the refinery's production of high-quality,
low-sulphur gasoline, and diesel by more than 38 percent.

Sarens was chosen by NIS/CB&I to perform the load-out,
transport, jacking, skidding, and lifting of equipment, two coke
drums under a pipe rack, and steel constructions at Pancevo in
Serbia. To undertake the project, the team deployed:

CC6800-1

TC2800

SCX2800-2

Skidding and jacking system

48 axles of SPMT

CC6800 with SSL 114m configuration, came from Rostock by road;
SCX2800 with MB 48.75m configuration, came from UK by ship to
Rotterdam and then by road to Pancevo. All other equipment came
from Belgium by road. CC6800 was rigged in a congested area as
there was only one access road of 130m x 12m. All trucks had to
enter in reverse direction to be unloaded by the SCx2800, which
rigged the main crane. The equipment was ready to perform the lifts
in ten days.

The project comprised of two stages:

Un-load of refinery components in Azatora port with TC2800 and
transport to pre-dressing area, which took place in January
2018.

Transport of pre-dressed components to site and lifting with
SCX2800 and CC6800, which took place between March and April
2018.

The fifteen member crew placed all the components on top of a
concrete foundation making a total height of 91.5m. According to
Abderahim Bouazza, "For all the lifts, the crane had to pick up the
load in tandem, slew and crawl with the load up to 40m. It was a
challenging project to be performed in a very confined space with
each component being both heavy and huge. Our teams coordinated to
successfully complete the project under the guidance of our safety
manager."
